Abstract :
A new model for the HBT has been developed which solves for the electrical and photogenerated currents in the base, emitter, and collector. The model accounts for the discontinuity in the quasi-fermi level by defining an effective carrier interface velocity. Experimental and theoretical curves relating to the device behavior are presented and compared
